Title: Non-woven fabrics
Inventor: ATKINS HAROLD JEFFREY
IPC: D04H1/48
Filed: 1966-10-18
Abstract: 1,207,124. Fabric laminate. LANTOR Ltd. 18 Oct., 1967 [18 Oct., 1966], No. 46423/66. Heading B5N. A method of manufacturing a non-woven fabric comprises applying fibrous non-woven web to one or both faces of a stitch-bonded fabric consisting of or containing fusing thermoplastic fibres, attaching the web to the stitchbonded fabric by needle punching on one or both faces of the multilayer fabric, and subjecting the needlepunched fabric to heat treatment in at least selected areas sufficient to cause at least some of the thermoplastic fibres to melt. A non-woven web may be applied to each surface of the stitchbonded fabric, the needlepunching being effected after the application of each or both webs. The stitch bonded fabric consists of a web of fibres bound together by stitching with yarns or threads. The web of this fabric may include, as the thermoplastic fibres, fibres of vinyl chloride-acrylonitrile copolymer, polyethylene or polypropylene, which may be blended with non-thermoplastic fibres such as cotton or thermoplastic fibres with a higher melting point such as viscose rayon, nylon, polyester or polyacrylonitrile fibres. The stitching yarns or threads may be of cotton, viscose rayon, polyamide or polyester fibres, and are preferably stitched in a combined chain stitch and tricot stitch pattern. The fibrous non-woven web (or webs) may consist of cotton, regenerated cellulose, nylon, polyester, or polyacrylonitrile fibres or blends of two or more such fibres. The non-woven webs, and the web of fibres of the stitchbonded web may be formed by air-laying, carding, or crosslaying optionally with needlepunching, or garnetting, and the non-woven webs may include a bonding agent. The heat treatment may be effected without pressure, e.g. in an oven or by infra-red radiation, or in a heated platen press, the pressure being exerted overall or only in selected areas. The press may include a wire gauze to emboss the fabric. The surface of the finished fabric may be brushed or raised. The fabrics may be used as blankets, filters, or apparel, and are heat insulating.

Title: Torque control means for variable displacement hydraulic pumps
IPC: F04B49/08
Filed: 1965-11-09
Abstract: 1,056,655. Fluid-pressure servomotor systems. R.J. IFIELD PTY Ltd. Nov. 9, 1965 [Nov. 16, 1964], No.47575/65. Heading G3P. A control system for limiting the driving torque of a variable displacement pump comprises, a differential piston 1 having a spindle 2 for varying the displacement of the pump (not shown), a passage 3 connected to the pump outlet and communicating with the smaller piston chamber 5, with a chamber above a spool valve 7 and with a chamber 8 intermediate two lands of the latter, and a chamber 14 receiving fluid through a line 15 and adapted to be maintained at a pressure which is a function of the pump's displacement, such latter pressure acting on a diaphragm 28 at the lower end of the spool valve. In operation, increasing pump outlet pressure lowers the spool valve to exhaust the larger piston chamber 11 to line 13 and thereby moves the piston to the right to decrease the pump displacement. As the spindle 2 moves, it causes a cam 23 to progressively close a vent valve 16 to raise the pressure in chamber 14 to thereby return the spool valve to its neutral position. Decreasing pump outlet pressure causes leftward movement of the piston and a lowering of the pressure in chamber 14. An orifice 24 or a relief valve 25 determines the maximum pressure rise in chamber 14 and hence the maximum pump output pressure; alternatively, the vent valve may have a predetermined minimum area. The supply to chamber 14 may be from a variable displacement pump driven by the same engine, from a fixed displacement pump via a flow proportioning valve or from a centrifugal pump or constant pressure source via a variable orifice that assists in maintaining the pressure at the desired function of displacement. There may be a number of vent orifices in parallel from chamber 14 with means enabling the operator to select which of those orifices is to be in use at any one time. When the pump being controlled provides forward and reverse flows the cam may be double faced or two vent orifices may be used, one being operative in the forward direction and the other in the reverse direction. The pump outlet pressure and the pressure in chamber 14 may act in the same direction on the spool valve against a spring or a compressed air load, in which case the pressure in chamber 14 is directly proportional to pump displacement instead of inversely proportional. The vent valve may alternatively comprise a plain cylindrical plug slidable relative to a V- shaped port or a plug with a plurality of graded ports slidable in bore having a plurality of ports.

Abstract: 1,096,327. Overrunning brakes for trailers. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK KOMM. GES.]. Nov. 11, 1965 [Feb. 20, 1965], No. 47905/65. Headings F2E and F2F. An overrunning brake for a motor vehicle trailer, of the kind including a master cylinder disposed in the draw-bar tube and connected by brake lines to the trailer brake cylinders, has disposed in the circuit between the master cylinder and the brake lines a distributer valve having a valve piston 12 loaded by a spring 11 so that a sealing disc 17 is urged to close inlet opening 8 from the master cylinder when the brake is off, whereby the brakes will only be operated when a given threshold value of the inlet pressure is exceeded, this value being higher than the back pressure necessary to open the valve should expansion occur in the brake lines when the brake is off, e.g. through heating, owing to the relationship between the area of the piston exposed to such back pressure and the area of the seat covered by disc 17. When the brakes are being applied inlet pressure acts over the whole area of piston 12, causing it to remain in an unobstructing position against a stop sleeve 16.

Title: Preparation of cheese
Inventor: KILPADI VIVEKANAND SAKHARAM
IPC: A23C19/04
Filed: 1964-11-25
Abstract: In the preparation of cheese, milk is reacted with a coagulating agent to produce a curdled product, the curd is substantially separated from the whey, and a protease is added to the separated curd to assist the cheese to ripen.  The protease is preferably papain or comminuted frog pancreas, preferably in an amount of 0.001-5.0% wt at 25-37 DEG C.  The protease may be added at any convenient time after separating the curd and the whey. After treatment, the curd may be washed with an aqueous solution of a salt, such as 0.5-5.0% sodium chloride, preferably at 25-50 DEG C.  If required, the calcium content of the milk may be reduced from its natural level, for example by addition of calcium-free casein, which may have been precipitated from milk by addition of acid, either before or after the protease treatment. After the treatment the curd may be heated to inactivate the protease.  In examples the product was melted with a salt mixture containing sodium chloride, sodium citrate, and citric acid, and colouring and flavouring materials were added, to give process cheeses.

Filed: 1963-12-14
Abstract: 1,107,707. Digital electric calculating. ELECTRIC & MUSICAL INDUSTRIES Ltd. 14 Dec., 1964 [14 Dec., 1963], No. 49477/63. Heading G4A. [Also in Division H4] In Specification 952,737 the rotation of the resolved rectilinear time base in a radar P.P.I. is effected by two groups of digital signals representative of the sine and cosine of the angular position # R  of the aerial produced photo-electrically at the aerial and transmitted to the P.P.I, position. In the present modification the digital information transmitted from the aerial direct represents # R  and sin # R , cos # R  binary signals are computed from that representation. # R  appears on twelve input conductors 1 as a parallel binary coded signal and is fed to a register 4 via gates 3. Shortly after the beginning of a radial scan black-out pulse (S.B.P.) on line 14, device 7 opens AND gate 17 to pass clock pulses to a binary counter 18 which produces output pulses, related in frequency as powers of two, by separate conductors to corresponding inputs of arrays 22, 23 of AND gates, the latter being controlled by binary reversible cosine 24, and sine 25, counters; counters 18, 24, 25 are re-set by the beginnings of S.B.P.'s. Counting sense in counters 24, 25 is controlled via gates 62, 63 and initially counter 24 counts downwardly and counter 25 upwardly. When the total in a counter reaches zero, respective stage 29, 30 changes state. During the S.B.P. the composite pulse train on circuit 35 passes via gate 37 to the input 27 of sine counter 25 and similarly for circuit 36, gate 38 and input 26 of cosine counter 24. It can thereby be shown that the total in counter 24 represents cos # and that in counter 25 represents sin #, the angle # being represented'by the total in counter 18 starting from zero just after the beginning of the S.B.P. and increasing steadily during the S.B.P. at a rate proportional to the clock pulse frequency. The contents of register 4 and counter 18 are compared in an array of gates 5 and a gate 6 of threshold twelve which produces an output when # = # R ; this output re-sets device 7 and thereby closes gate 17. At the end of the S.B.P., i.e. at the start of the next radial timebase scan, a signal is applied to a gate 12 to permit further clock pulses, after frequency division, to pass to counter 18; gates 37, 38 being closed and gates 44, 45 now being opened, digital-to-analogue converter counters 48, 49 are energized, the requisite orthogonal deflection voltages being afforded by resistor matrices R, R<SP>1</SP>.

Abstract: 1,269,149. Control of two A.C. motors. GENERAL ELECTRIC CO. 8 Oct. 1969 [22 Oct., 1968], No. 49482/69. Heading H2J. [Also in Division G3]  An ingot is mounted on a carriage 10 for transport between points A, B, by means of D.C. motors 16, 17, which are coupled to drums 13, 15, associated with cables 12, 14. Each motor tends to pull the carriage in opposite directions when negative and positive reference signals are applied respectively to the summing junctions 21, 23. Firing circuit 22 triggers rectifier 19 to energize motor 16, while firing circuit 24 triggers rectifier 20, to provide an equal amount of power to motor 17. The carriage is moved towards the point A when a positive signal is applied to summing junction 25 and passes through amplifier 26, filter 27, and diode 28 to junction 23 whereby rectifier 20 increases the power delivered to motor 17. The positive signal at junction 25 also passes through filter 29, but is normally blocked by diode 30. However, resistor 34 may be adjusted to allow a reduced signal to reach the junction 21 so that the power delivered to the motor 16 is reduced. This permits the motor 17 to overcome the inertia of the driven parts. The carriage is reversed by applying a negative signal to junction 25, so increasing the torque of motor 16 which winds the cable 12 against the pull of the cable 14 under the influence of the counter-torque of motor 17. A tachometer generator 18 is coupled to either of the motors and provides a feedback signal to junction 25 for speed stabilization. Negative feedback is provided by circuits 31, 32, to limit the current output of the rectifiers 19, 20.
